TPS92641: Constant current regulator for TEC (Peltier)drive in parallel

Ryo Akashi

Part Number: TPS92641

Hi experts,

For TEC (Peltier) driver, I plan to use LED driver as constant current source. TPS92641 is good for constant current regulator.

To drive TEC(Peltier), it is needed for much current (~5A), so I would like to operate some LED drivers in parallel.

Is it possible?

Thanks and best regards,

Hi Ryo,

The TPS92641 is not parallel-able.

Thanks Tuan

Hi Ryo,

The TPS92641 is a controller so the external FET's and circuitry determine the output current. Depending on the requirements, you should be able to use one part to do this.

Thanks Tuan
